Context. It has been suggested that the escape fraction of hydrogen ionizing photons (f(esc)) from galaxies is evolving with time, but the picture is far from clear. While evidence for significant ...

Low-redshift Lyman continuum leaking galaxies with high [O iii]/[O ii] ratios (2018, methodology): “Now with our new LyC leakers we have in hand a sample of sixteen galaxies with a wide range of O32 ∼ 0.5 – 27 (Leitet et al. 2013; Borthakur et al. 2014; Leitherer et al. 2016; Izotov et al. 2016a,b, 2018, this paper).”
Lyman-α spectral properties of five newly discovered Lyman continuum emitters (2016, background): “%) have been found during the last decade (Bergvall et al. 2006; Leitet et al. 2013; Borthakur et al. 2014; Leitherer et al. 2016, Puschnig et al., submitted).”
Using Lyman-α to detect galaxies that leak Lyman continuum (2014, methodology): “Our sample was selected from Bergvall et al. (2006), Heckman et al. (2011), Leitet et al. (2013).”
J1154+2443: a low-redshift compact star-forming galaxy with a 46 per cent leakage of Lyman continuum photons (2017, methodology): “Haro 11 was observed only with FUSE (Leitet et al. 2013) and has still to be confirmed with COS observations.”
The First Billion Years project: the escape fraction of ionizing photons in the epoch of reionization (2015, background): “Except for two objects (Leitet et al. 2011, 2013), in the local Universe no ionising radiation has been detected directly (Leitherer et al. 1995; Deharveng et al. 2001), although some objects show indirect evidence of photon leakage (Heckman et al. 2011; Zastrow et al. 2011).”
Ionization state of inter-stellar medium in galaxies: evolution, SFR-M * -Z dependence, and ionizing photon escape (2013, background): “Emission line fluxes for Haro 11 and Tol 1247−232 are obtained from Bergvall & Östlin (2002) and Terlevich et al. (1993), respectively, and stellar masses from Leitet et al. (2013).”
The difficulty of getting high escape fractions of ionizing photons from high-redshift galaxies: A view from the FIRE cosmological simulations (2015, background): “…are broadly consistent with the wide range of observationally constrained escape fractions measured from variant galaxy samples at z = 0–3 (e.g. Leitet et al. 2011, 2013; Cowie et al. 2009; Siana et al. 2010; Bridge et al. 2010; Iwata et al. 2009; Boutsia et al. 2011; Vanzella et al. 2012;…”
Detection of high Lyman continuum leakage from four low-redshift compact star-forming galaxies (2016, methodology): “Two of these galaxies were observed with the HST/COS (Borthakur et al. 2014; Leitherer et al. 2016), one galaxy with the Far Ultraviolet Spectroscopic Explorer (FUSE) (Leitet et al. 2013) and one galaxy with both the HST/COS and FUSE (Leitet et al. 2013; Leitherer et al. 2016).”
Fluctuating feedback-regulated escape fraction of ionizing radiation in low-mass, high-redshift galaxies (2017, background): “In the Local Universe, extremely few LyC leaking galaxies have been found, all exhibiting low escape fractions fesc ∼ 1−10% (Bergvall et al. 2006; Leitet et al. 2013; Izotov et al. 2016, see also Heckman et al. (2011)), and for some other candidates, only upper limits could be secured (Heckman et…”
